[solved] alsa not working after kernel-upgrade

My Sound is not working after i upgraded to kernel 3.4.4
I'm using alsa and everything was fine before the upgrade, no i can't get alsa to work properly.

The first issue after the upgrade was the 'Unkown hardware' error wich i fixed with the

# alsactl -f /var/lib/alsa/asound.state store

command from the wiki. Now no more errors appear on startup, but sound is still not working.

I can't seem to find the error, so i hope someone can help me here.

speaker-test gives the following error:

speaker-test -c 2

speaker-test 1.0.25

Wiedergabe-Gerät ist default
Stream-Parameter sind 48000 Hz, S16_LE, 2 Kanäle
Verwende 16 Oktaven rosa Rauschen
ALSA lib pcm_dmix.c:1018:(snd_pcm_dmix_open) unable to open slave
Fehler beim Öffnen des Gerätes: -2, Datei oder Verzeichnis nicht gefunden

most other programms are throwing a similar error, like device not found or file or directory not found or unable to open device

i checked the alsamixer settings where all channels are unmuted and up.
however in alsamixer there are only two channels for output, PCM and Beep.
I'm not really sure if there were more before the upgrade (like master or left and right)

Here's some additional output, which seems fine to me:

from this i think my sound card is detected and loaded properly, so where could the problem be ?
if you need any additional output or logs, feel free to tell me where to look.

Thanks in advance for any help.

Re: [solved] alsa not working after kernel-upgrade

i didn't change anything, except updating the system today, but now the sound is working again
a new error appeared on startup:

...
Sun Jul  1 19:56:54 2012: :: Restoring ALSA Levels    [BUSY] Found hardware: "HDA-Intel" "Realtek ALC880" "HDA:10ec0880,08800000,00100800" "0x1025" "0x007d"
Sun Jul  1 19:56:54 2012: Hardware is initialized using a generic method
Sun Jul  1 19:56:54 2012:    [FAIL] 
...

anyway, sound is working again without problems so i mark this as solved....

Re: [solved] alsa not working after kernel-upgrade

I was having sound problems which I fixed by putting the word alsa in the etc/rc.conf file in the daemons array
